"The Prime Minister held separate telephone conversations earlier today with the US President Donald Trump and the French President Emmanuel Macron.

"They agreed that reports of a chemical weapons attack in Syria were utterly reprehensible and if confirmed, represented further evidence of the Assad regime’s appalling cruelty against its own people and total disregard for its legal obligations not to use these weapons.

"They agreed that the international community needed to respond to uphold the worldwide prohibition on the use of chemical weapons.

"They agreed they would continue working closely together and with international partners to ensure that those responsible were held to account."
